Clinical and functional outcomes of surgical treatment of grade III ulnar collateral ligament injuries of thumb metacarpophalangeal joint.

Objectives: The aim of this study was to compare the clinical and functional outcomes of three surgical techniques (subperiosteal suture, bone anchor and direct repair) for the management of severe acute ulnar collateral ligament injuries of the thumb metacarpophalangeal joint with a minimum of 1 year follow-up.

Material And Methods: Between 2015 and 2020, 230 collateral ligament injuries required surgical treatment in our department. After the inclusion and exclusion criteria were applied, 100 were included in the study.

Recent and chronic sprains of the First Metacarpo-Phalangeal Joint.

Sprains of the first metacarpo-phalangeal joint (MCPJ) are a common form of hand injury that mainly affects the ulnar collateral ligament. Although the diagnosis is made on the physical findings, radiographs must be obtained and ultrasonography or magnetic resonance imaging (MRI) is necessary in some cases. If the joint is unstable or a bony fragment is displaced, surgery must be performed within 4 weeks after the injury.

Arthroscopic Scapholunate Synthetic Ligamentoplasty.

The scapholunate ligament is made of 3 portions: proximal, volar, and dorsal. The latter is the major stabilizer of the scapholunar pair, and its lesion is bound to cause a destabilization of the carpus, as well as scapholunar diastasis, dorsal intercalated segment instability, then eventually SLAC (i.e.
